To determine if 8245 is a prime number or a composite number, we simply look at the factors for 8245.
If the factors of 8245 are only 8245 and 1, then we know that 8245 is a prime number. Otherwise, 8245 is a composite number.
To explain better, if 8245 is only divisible by 1 and 8245, then it is a prime number, and if 8245 is divisible by more than 8245 and 1, then it is a composite number.
The factors of 8245 are as follows:
